Acoustic streaming generated by airborne ultrasonic phased arrays plays a critical role in the performance of advanced ultrasonic technologies, including midair haptic feedback, odor delivery, and acoustic levitation. Researchers at University of Tsukuba have developed a predictive model for acoustic streaming in phased arrays by integrating three-dimensional acoustic and fluid simulations.
